Specification of Letters Patent.

Patented Apr. 13, 1920.

Application filed June 20, 1818. Serial No. 240,940.

2 '0 all whom it may concern Be it known that I, HARRY D. LATHRoP, a citizen of the United States, and a resident of the cit of Chicago, county of Cook, and State of llinois, have invented certain new and useful Improvements in Cargo-Stops, of which the following is a specification.

My invention relates to improvements in cargo stops, and has for its object the to duction of a device of this character, w ich will be of durable and economical construction, and which may be readily and easily applied to cfl'ect secure anchoring of a cargo in a freight car or other similar place.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawin s forming a part of this specification, and in which,

Figure l, is a horizontal section through one end of a conventional freight car in connectlon with which 1s shown a cargo stop embodying the invention,

Fig. 2, an enlarged top plan view of one end of the cargo stop,

Fig. 3, a central vertical longitudinal section of the construction seen in Fig. 2.

Fig. 4, a section taken on line 4-4 of ig. 5 a view similar to Fig. 1, showing a slightly modified form of construct on,

and y 1 Fig. 6. an enlarged section taken on substantlally line 6-6 of Fig. 5. The preferred form of construction, as illustrated in the drawin s, comprises an elongated channel bar 10 o a length adapting the same to be received in a freight car, :he length of said bar being slightly less .han the width of the interior 0 the car. jooperating with the opposite ends of said far are legs 11, pivotal y connected thereto )y bolts 12 and cooperating nuts 13, the ar- 'angement being such that said legs .w1lI be .dapted for pivotal adjustment to any 1nlined position desired in order to support he bar 10 at various elevations. Throu vdjustinent of nuts 13, the legs 11 may acked in any position of angular ad ustlent. Slidably mounted in each end of bar 10 i a jaw 14,0f inverted'T-form in cross sec- .on, said jaw being held in place in the channel of member 10 by means of a pair of angular holding members 15 which are secured to the bar 10 by means of bolts 16 and cooperating nuts 1' The bolts 16 serve also as supports for the jaw 14, the latter being adapted to slide thereon, as clearly seen in Figs. 3 and 4, friction being thus reduced to a minimum.

Coiiperating with each of the jaws 14 is an operating lever 1.8, which is fulcrumed at 19 to one end of an anchoring and fulcrum-forming member 20, which is of sub stantially U-shape, with the ends of the U pivotall connected with said lever, the bight of the U bein adapted for engagement with anyone 0 a lurality of spaced notches 21 formed in t e upperedges of themembers 15. With this arrangement it will be seen that the lever 18 may be shifted longitudinally of the bar 1 so as to osition the fulcrum thereof at any desired osition to adapt the device for employment in connection with cars of various widths. The lever is connected with the rearward end of the corresponding jaw 14 at 22 so that. said jaw will be longltudinally shifted upon pivotal movement of the lever. The arrangement is such, as will be seen, that when the levers are rocked inwardly, that is, toward each other, the jaws 14 will be moved outwardly for en agement with the opposite sides or walls of t e car A in connection with which the device is employed. Through the shifting adjustment permitted the anchoring fulcrum-formin members 20, as just described it will Ee seen that the jaws 14 are ada ted to be adjusted bodily longitudinally of t e bar 10 in order to adapt the device for use in connection with cars of various widths. The outer ends of jaws 14: are formed with points 14', to sink into the surfaces engaged, thus reventing any accidental disengagement o the jaws. Each lever 18 is .so mounted and connected with the corresponding member that when said lever is rocked inwardly and downwardly to its lower terminal of movement, the same willhave passed just beyond the dead center, whichtwill serve to automatically lock the lever in operative position, it being clear sure exerted upon the jaws, a r said levers have reached their operative position, tends only to rock said levers downwardly -or, in other words, to hold said levers in operative position.

which are adapted that an inward pres- In use, the cargo or articles 13 which are to be anchored or held a ainst shifting in the railway car, are crow ed together so as to snugly engage with one another. The device is then placed against the cargo and the levers 18 adjusted to effect en a ement of the jaws 14 with the sides 0 tie car, thereby serving to lock the device to the car and hence to securely lock the cargo against any shiftin This locking of the cargo prevents acci ents and damage which otherwise frequently occur in a pxartmlly loaded car, since in the latter case t e cargo will shift under the severe jolting and jarring to which the same is subjected in the movement of the car. With the construction in question however, all shifting or rela tive movement of the cargo is positively revented, and thus the objection referrer to obviated.

If desired, the device as described may be provided with an additional or auxiliary brace member 23 for bracing the center of the bar 10. In this case the member 23 will be connected at 24 with the bar 10 midway the ends thereof in a manner permitting of universal pivotal movement of the member 23 so that the latter, when not in use, may be rocked upwardly to lie parallel with the bar 10. The ivotal connection of the legs 11 with the bar 10 also permits of said legs being rocked upwardly to assume positions parallel with said bar when the device is not in use. The member 23 will be provided at its lower end with a jaw 25 of the same construction as the jaw 14 above described, the jaw 25 bein longitudinally shiftable through the me ium of a lever 26 mounted and arranged in precisely the same manner as the levers 18 above described.

While I have illustratcil and described the preferred form of construction for carrying my invention into effect. this is capable of variation and modification without departing from the spirit of the invention. I, there ore do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications us come within the sec e of the appended claims.
